2007 Honda Civic Si Sedan

Fog Light Assembly: PN# 08V31-SNA-100

The first installment of our street-legal Si is the perfect companion for those of you who've just recently sprung for a new car purchase and are curious how to go about modifying it, without voiding the warranty. It's simple: most dealers offer Honda's Factory Performance line (like Penske Honda, who sold us ours) as one of their accessory options. This means these are parts you can add to your car easily, without worrying about your warranty one bit because you are guaranteed Honda quality. Although most of the parts offered are cosmetic, Honda does produce performance-related accessories, like lowering springs and exhausts. But for the four-door Si, you're limited to a mild aero kit, fog lights and, from what we're told, lowering springs have just been approved for release (we're awaiting confirmation). Follow along as we give our Project Si the first of its modifications, starting with the HFP aero add-ons, upsized wheels and foglights.

Front Under Spoiler/Fog Lights

	1. Begin by disconnecting the negative terminal from the battery. Remove the plastic panel that covers the radiator to access the bolts that keep the front grille attached to the radiator support/chassis. Locate the remaining bumper bolts so you can remove the front bumper from the car.
2. Use a rack to prop the bumper onto. Mask off the fog light locations on the bumper with masking tape to prevent it from being cut into (yes, the factory bumper needs to be cut in order to accept the fog light housing).	3. Flip the bumper over (since you'll be cutting into it from the back side).Using a saw blade, cut into the designated Honda areas and along the outline of the plastic; these marks are usually identified with circular preset marks (see inset photo for closer detail).
4. Once the unwanted plastic is cut away, you're left with an open space that'll be filled with the fog light. Do yourself a favor and test fit the fog light trim piece before putting it together. After you've ensured it fits, go ahead and assemble the fog light.		5. Attach the wiring harness to each fog light connector, then secure the harness to the backside of the bumper using the supplied zip tie/clips (very cool; you'll see). Connect the remaining portion of the wiring harness to the connectors located just in front of the wheel well. Reinstall the front bumper and install the front under spoiler using the supplied double-sided tape (they're already pre-mounted to the spoiler; peel the tape cover back) and secure it with the supplied screws/bolts.
6. Now it's time to connect the switch harness (white/red and blue terminals) into the vehicle's white 34-pin connector, located underneath the steering column. Remove the lower dashboard cover to access the green 42-pin connector, white 34-pin connector and blue 21-pin connector from the fuse box; remove them all so you can get to the white connector. Route the switch harness above the vehicle knee bolster (refer to instruction diagram) and plug the relay into the switch harness relay block. Locate the 1-pin connector blue taped to the vehicle harness; plug them together.	7. Last, you have to switch out the original turn signal for the one that comes with the fog light kit; it has a ring switch on it to turn the lights on or off. Remove the plastic steering column covers to access this area; there are two screws you must undo to take the original lever off. Install the new lever in the reverse order of removal. Install the 20A fuse into the fuse box, which is also accessible from under the dash. Now your fog lights are done!
